Write to a customer after 24 hours

After 24 hours without a message from the customer, WhatsApp only lets you send a template it has approved.

Steps

1. Prepare the template in Sales › Templates (see Prepare a template). WhatsApp often approves it in less than an hour.
2. While the 24 hours are running, the reply box shows You can reply freely for another …, with the time left. After that, the reply box is replaced by Free replies are over (24 hours passed). Click Choose a template. You can also write an Internal note for the team.

3. Choose the template, fill in its Variables if there are any, check the preview, then click Send template.
